Monitor vCenter Server Services

When you are logged in to a vCenter Server system that is part of a connected group, you can monitor the health of services running on each server in the group.

The vCenter Service Status screen enables you to view the following information:
A list of all vCenter Server systems and their services, and vCenter Server plug-ins.
The status of all listed items.
The date and time when the last change in status occurred. Any messages associated with the change in status.

Incorrect answer: The environment has 400 ESX Hosts 32-bit OS for vCenter will only support 200 Hosts and 2000 powered on VM’s ( 3000 registered ).
A single instance of vCenter Server 4.0 manages up to 300 hosts and 3000 virtual machines and with Linked Mode you can manage up to 1,000 hosts and 10,000 virtual machines across 10 vCenter Server instances.
